13th Month Pay Calculator
Total basic salary for the year ÷ 12: the exact PD 851 formula, with the ₱90,000 tax-exempt threshold applied.
Sum of basic pay only: excludes overtime, allowances, and other benefits.
Note: Under PD 851, only the amount above ₱90,000 is subject to withholding tax. If you were hired or resigned mid-year, use your actual total basic salary earned during your employment period, not a full year's salary. This is a free estimation tool; it does not send your data anywhere.
